I stopped in the Mekong out of curiosity last week and had the beef Pho. It was excellent, with the freshest of ingredients. The seasoning was just right, and the portion was quite large. I went back again yesterday to try a different dish, the Vietnamese Chicken soup, which was just as tasty. It was filled with rice noodles, chicken, vegetables and served with a side of herbs, lime, jalapenos and bean sprouts to add to the soup as desired. Many diners around me were having interesting looking stir fries, rice dishes, and curries. Everyone seemed to really enjoy the food. The service is excellent. If you go at lunch, be prepared to wait. I recommend going a bit before noon or a bit later. They are closed on Mondays
If you have a few minutes, you might want to check out the Oasis World market next door, which stocks foods and other items from around the world you certainly won't find in your local food market.
